Job Summary

Coreshells metallurgical Silicon anode technology delivers high capacity fast-charging and superior safety. Our low-cost liquid-phase nano-coating addresses critical electrode-surface degradation issues and enables batteries with a Silicon-dominant anode that have higher energy density superior intrinsic thermal safety and significantly lower cost/kWh compared to current LIBs. Our Si anode material is lower than the cost of graphite and 100% domestically sourced. We strive to transform the global automotive market by enabling low-cost and long-range EVs as a first step towards net-zero sustainability in the near future.

Core Responsibilities: We are seeking a Product Engineer to drive new product introduction (NPI) by owning both the engineering definition and hands-on execution required to mature battery technology from concept to manufacturable commercial offerings. This role is deeply involved in the physical realization of products that meet customer requirements including assembling prototypes developing test protocols executing validation tests and generating the data needed for robust specifications. The Product Engineer will work directly with materials cells modules and contract manufacturers serving as both the technical architect and the primary experimental operator to rapidly iterate designs reduce risk and accelerate time-to-market.

Requirements:

Define test strategies write and execute detailed test protocols and procedures for customer-relevant performance safety reliability and cost validation
Specify instrumentation test conditions pass/fail criteria and data requirements
Review and interpret test results identifying trends risks and design gaps

Assemble battery cells modules and packs for prototype and pilot builds as needed including fabricating or sourcing fixtures instrumentation and test articles required for validation
Identify and resolve assembly handling and repeatability challenges during early builds

Collect analyze and interpret test data to refine specifications optimize design assumptions and lead failure analysis and root-cause investigations
Drive engineering changes informed by empirical data cell build feedback and manufacturability insights

Work directly with contract manufacturers on prototype and pilot builds resolving design and process issues to support design-for-manufacturing (DFM) and design-for-cost efforts by evaluating yield process capability and cost drivers

Develop build instructions BOMs and acceptance criteria to support repeatable prototype builds
Develop implement and update performance lifetime and cost models based on experimental results
Generate and maintain technical documentation to support prototype-to-product maturation

Requirements:

Bachelors degree in Mechanical Engineering Electrical Engineering Materials Science Chemical Engineering or related field
5 years of experience in battery systems energy storage or related electro-mechanical product development
Demonstrated experience leading NPI from concept through prototype and into early production
Strong understanding of lithium-ion battery performance safety and degradation mechanisms
Experience defining and interpreting test plans and validation data using standard battery cycling equipment
Ability to work hands-on with hardware while maintaining system-level engineering ownership
Familiarity with battery standards and compliance testing (UL IEC UN38.3 SAE etc.)
Experience with modeling tools for battery performance lifetime or cost (e.g. PyBaMM AVL or equivalent)
